摘要
随着人们生活水平的提高,对室内污染越来越关注,应“中国室内环境监测委员会”提出的需求,通风气象指数于2006年6月首次向北京公众发布,文章就首先研发并投入业务使用的夏季通风指数给出了详细论述。通过对2005年夏季(6~8月)的各气象要素(气压、温、湿、风、能见度、天空状况等)资料共1790个数据做检验分析,最终选取体感温度为主要预报因子并综合考虑夏季特殊天气条件和风力以及污染的影响,得出夏季通风指数在一天中7个时段的预报公式,并划分出相应的指数等级。
With the enhancement of people's living standards, indoor air pollution attracts broad concern. The ventilation index (Ⅵ) began to be released to the public operationally from June 2006. By testing and analyzing 1790 data records, including pressure, temperature, humidity, wind, visibility, and weather phenomena, apparent temperature is selected as a main forecasting factor. Different forecasting formulas of summer Ⅵ in seven periods (05:00 to 08:00, 08:00 to 11:00, 11:00 to 14:00, 14:00 to 17:00, 17:00 to 20:00, 20 : 00 to 23 : 00, 23 : 00 to 05 : 00) are developed, considering the influences of summer unusual weather phenomena and wind speed, and the corresponding grades of Ⅵ are classified.
